This geotechnical memorandum provides final design and construction recommendations from the Western Federal Lands Highway Division (WFLHD) for the Western Heritage Byway – Swan Falls Road project in Ada County, Idaho. The project involves shoulder widening and pavement rehabilitation along a five-mile stretch of Swan Falls Road, alongside improvements to the Dedication Point parking area, including a new vault toilet facility. Geotechnical evaluations focused on an existing rock through cut requiring expansion to accommodate shoulder widening. Site observations and kinematic stereonet analyses conducted on the west and east cuts—which consist of Pleistocone-age basalt formations and surficial silt loam soils—indicated low structural failure potential. Consequently, the memorandum recommends a maximum cut slope angle of 1V:1H for the west cut and a gentler 1V:2H slope for the soil-heavy east cut to mitigate rilling and gullying. Due to low historical rockfall activity, rockfall catchment ditches are not required. For construction, contractors must be prepared to excavate variable soil depths, cobbles, and large basalt boulders up to five feet in dimension. While blasting is permitted, the excavation method and required material testing remain the contractor's responsibility. Lastly, the proposed vault toilet site at Dedication Point, underlain by Turbyfill fine sandy loam, showed no surficial bedrock, though sporadic basalt boulders are present.

This safety assessment memorandum from the Western Federal Lands Highway Division outlines recommended safety improvements for the Swan Falls Road widening project (ID FLAP ADA 2019(1)) in Ada County, Idaho. The project's primary goal is to pave 5-foot shoulders to improve bicycle safety and reduce roadway departure crashes along the sole access corridor to the National Conservation Area and Swan Falls Dam. Based on crash data showing high rates of single-vehicle runoff crashes, several safety countermeasures are proposed for the final design. Key recommendations include implementing 5-foot paved shoulders, installing shoulder rumble strips with gaps for bicycle safety, and upgrading curve warning signage with advisory speed plaques on four sub-standard horizontal curves. Additionally, due to a vertical crest curve that limits stopping sight distance to 40 mph on the 55 mph corridor, the installation of "Hill Blocks View" warning signs with 40 mph advisory plaques is recommended. Several countermeasures were dismissed following partner feedback at the 70% design milestone. Centerline rumble strips, 6-inch wide edge lines, reflective sign-post strips, and in-lane curve pavement markings were removed due to maintenance concerns and localized constraints. The design defaults to Type B waterborne pavement markings and perforated square steel tube posts. Ada County must provide final confirmation on the use of shoulder rumble strips, sign panel materials, and the proposed warning signage.

This federal document is a Brand Name Justification and Approval (J&A) for the Federal Highway Administration’s (FHWA) Western Federal Lands Highway Division (WFLHD) regarding the reconstruction of Swan Falls Road on the Western Heritage Byway in Idaho. The J&A justifies the sole-source acquisition of specific brand-name products valued at $150,000 for public facility improvements at Dedication Point. The required products include two RJ Thomas Mfg. Co. Inc (Pilot Rock) picnic tables ($5,000), one CXT Incorporated vault toilet ($100,000), and one Poligon shade shelter structure ($40,000). The FHWA cites FAR 11.204 and FAR 6.103 authorities for this restriction, explaining that these specific brands are essential to maintain aesthetic continuity with the Bureau of Land Management’s (BLM) existing corridor infrastructure. Additionally, utilizing these brands maximizes operational efficiency because BLM maintenance technicians are already trained and equipped with the specialized tools and replacement parts required to service these exact models. Although the specific products are restricted by brand name, the overall project will be competed as a task order solicitation on SAM.gov to ensure fair and reasonable pricing through subcontractor competition. The document concludes with detailed technical specifications for each of the three approved items, outlining specific dimensions, colors, and materials to match existing site features.
